Deskripsi

Twin nucleation in face-centered cubic metals with high twin-fault energies should theoretically be unfavourable, but instead twinning is very often observed. Here, the authors report a new twinning route in nanocrystalline platinum that bypasses the high twin-fault energy barrier using closely spaced partial dislocations.
